Be it' known that I, SAMUEL L. Tacoma citizen of theUnited States, residingin the cityand countyof Philadelphia, inthe Stateof Pennsylvania, have invented certain new and useful Improvements in Apparatus for Filling Cans or other Receptacles, of which the following is a specification.

It-is the object of my'invention to providean apparatns'for filling cansor other-receptacles with paint or other liquid or semi-liquid material, of simple and inexpensivecom f struction, easy of manipulation, rapidgin operation, and adapted to fill cans to'a predeterminedilevel more accurately than has been possible with kindred apparatus as hereto fore constructed and arranged.

A further-object is the organization of the apparatus in such manner or formthat after having been employed for examplein filling cans with paint; of a selected, color, it may, upon the removal and replacement of easily detachable parts, be employed in filling cans n with. paint of an entirely d-iflerent color without'causing admixture of remnants of the paint-first referred to. with the second lot or mass.

- A further object is the provision of an ap{ paratus of this class by the aid .of which'not only may cans of uniform selected cubic'dim'ensions be accurately supplied with contents to a selected level, but also a series of cans of graduated capacities may be accu Y rately supplied at one operation with con-.

tents to selected levels, at predetermined distances from their respective tops. In the accompanying drawings I show, and

herein I describe, a good formofa convenien t embodiment of my inventio n'the particular subject-matter claimed as novel being hereinafter definitelyspecified'.

In the accompanying drawings,

1 is the base frame of, the machine provided l atiopposite sides with a pair-of standards des-- ignated 2 and 3 i'espectively, said standards being united at the top by'the cross member 4." Said members2-and 3 -are. provided-at their respective topswith the'wing plates designated 5 and 6 respectivel'y; ;1 Of course, any "suitablef ramework' maybe employed.

The base frame is provided with a-pair of rails-7, on which is mounted a wheeled carrier Sy designedto support. two sets of eight cans each,- the apparatusherein depicted l1appening to be one adapted to fill eight cans at a time.

Through-theprovision of the carrier 8 adapted to support'two sets of cans, I am enabled,

while the machine is chargingone set,.to re-' move from the carrier the cans .previously filled and to substitute thereforeight-cans to befilled. v Thereupon as soon as theeightcans of one set are filled, the carrier is caused to traverse.

to the opposite end of the machine, carrying too the filled-cansout from beneath the" filling apparatus, and'the empty'cansjustplaced-in position on the'carrier forwardinto-positionl beneath said apparatus.

When the carrieris at one end of the rails, one end portion of the carrierwith Sto'. the distant end of the way.-

The carrier in the organization depicted, is in its travel from end to end of its ways or. rails, always partly beneath the filling apparatus and partly out from beneath said apthe cans thereon is beneaththe'filling apparatus and the other end portion with the cans thereon out beyond .said.lapparatus, as shown in Figure 1, and when at the other end of'the rails said first mentioned end portion willbe the second mentioned end portion will be in As a convenient means for occasioning the required travel in opposite directions ofsaid wheeled carrier, I arrange on suitable bearing's on the upright 2 the rock shaft 9, the upper end of] which is provided with an operating arm 10 and the lowerend'oi. which is To. the outer end of said arm tante'nd of which link is .in turnjpi'votally connected to aproje'ction 13 extending later ally from the carrier.

and in contact with the sieve of said reser- Said bar is secured free. for horizontal reciprocation in suitable slideways 51' at the respective ends of the receiving reservoir.

.As the paint is delivered to the supply res;

ervoir it descends through the sieve supported thereon and upon the hopper bottom of said reservoir from which it discharges through t-he'opening in said bottom to the delivery spout 18, from thence of course to the receiving spout 17 from which it flows directly into the filling reservoir 16. The paint or other material who supplied to .the'cans may, of course, if desired, be applied directly to the filling reservoir 16 without passing through the several parts just described.-

The brushes in their reciprocation act to' assist in forcing the paint through the meshes of the sie ve, and more particularly to climb nateany clots of paint or .masses of matter which would tend to clog up the sieve, or in terfere with the-flow of the paint to the cans.

The main shaft 24 of the machine is; as to its left hand end, provided with acrank arm 25, to a wrist pin on which is connected the inner end of a link 23. Said link 23 is as to .its outer end connected to a threaded -upright 26, which rises from thereciprocating 1 bar 22 to which the brushes 21 are'directly .connected. The outer end of said link-has an opening through which extends the up-l too per portionof saidupright 26; a nut threaded on said upright limits the descen-tof the endof the link. By adjustmentof said nut, the outer end of the link may be lowered to take up any lost motion in the movement-of.

said link.

The link 23 is, as shown in dotted lines in Figure 2, composed of two parts or members,

the meeting ends of which 'overlap and are joined by a pivot 84, with the ,result that the outer end portion of said link may be swung with're spect to said pivot to project to the opposite side of the machine, as shown in dotted lines in Figure 1. arrangement, when the standard 19, with the parts which it carries, is moved to the oppo site side of the machine, said link 23 may, without'other change than that of the swinging of its outer end portion upon or with respect to said pivot, maintain its working relations withrespect to the parts moved, that is As a result of this to say, continue to occasion, underthe' actua tion of the crank 25, the reciprocation of the bar 22. Preferably the brushes 21 are made fast to the bar 22 by means of threaded shanks 27 which extend through said bar, on which shanks above and below said bar are'p'l'aced regulating nuts. -Manif'estly', bythe'adjust -ment of said nuts, said shanks 27 maybe raised or lowered and the brushes attached to their "lower ends correspon'dingly raised Where the convenie-nce'of the movements of operators requires it, the reservoir 20, spouti 18, and associated parts may be moved to the opposite side of the machine, and work in said opposite side of the-machine. \Saidf-rame gular section, and be set in s'ui 19 may be, as to its supporting legi of rectanf tab 28 formed in thebase frame of the machine,

such brackets being arranged one at each side;

of the filling reservoir.-.

The reservoir 16 is supported upon the two bars 30 which at their upper portions are'provided with teeth and which I, therefore, term i tend.

rack bars, said bars being arranged for ver-.' tical slidingmovement in suitable ways 31 upon the respective inner faces'of the up-, rights 2 and 3. Saidrack bars each have at its lower end an inwardly projecting nose in the formof a'transversely extending bearing bar' 32, (see Figure 9) which bar directly receives the weight of the reservoir lfithrough the detachable bottom, whereof hereinafter,

beneath'the ends of which. said noses 32 '61:-

Upon the main shaft 24 are arranged the 'pinions 33 in mesh with the teeth of the rack bars, so that upon thelrotat ion-of said shaft the elevation or depression of said rack bars her, having near its upper end an external annular groove42 (shown in-dotted lines in-Figand the reservoir maybe effected.

The bottom'34 of. the/reservoir 16 I term the permanent bottom merely todistinguish it from the detachable bottom.-

'36 is a detachable bottom, as I term it, conveniently, although not necessarily, formed of two longitudinally extending members or plates placed edge to edge, the said members or plates being secured in this relation bybeing'rested as to theinrespectiveends upon,

and being secured to,the respective horizontal nose bars 32 carried by the respective rack bars. 4

' The detachable bottom thus rests upon the rack bar noses,-and intnrn supports the" weight of the filling reservoir ,16. The per- ,manent bottom is provided with a series of threaded shanks 41 (see FigureB) which 'extend downward freely-through suitable openings formed in the detachable bottom, and below said last mentioned bottomare provided with wing or other nuts.

those near the upright 3 being designated 60.

The upper ends of the arms 59 are pivotally secured tothe outer ends of the wing plate 5, p and the upper ends of the arms 60 are pivotally secured to the outer ends ofthe wing plate 6.

Said reservoir,and when-herein 1* to be filled with paint or other liquid-orsemi liquid, either deposited directly within it, or

supplied thereto by way of the parts 17, 18,

20,-the operation of which-last mentioned" parts has already been vsufiic iently set forth.

Rotation of the main shaft ingthe'appropriate direction will permit the descent' 'o'f the rack bars and the reservoir. and asseci-' atedparts.

-In the descent of said parts the lower edges or lips ofqthe air excluding collars 40 make contact with the upper faces'of the cans, each .such collar surrounding the receiving opening of a can, and in the continued descent of the parts such collars are-caused to press more and more firmly upon-the upper faces of the cans and thereby increase the effectiveness of the air seal. I r The timing of themovemeuts of the apparatus is such-that in the descent of the parts after the lips of the air excluding collars make contact with the'gfac'es of the.cans,,the

bars 56,- which theretofore restedo'nand' dehumans/am 731,526 Y I v The stops or collars 50 secured to-the air pipes 47, rcstor'come to rest-upon the new stati'onarybars 56 and said air-pipes 47 are thus caused to cease their descent. The

of the reservoir, said supply or filling con--' duits are freed so to speak fromsaid valves 49 which, stopped; and suspended with the I air pipes, are, of-conrse, unseated.

the filling. conduits into the cans, the ribs 48 serving to spread or distribute it therein, and the air displaced from said cans ascending through the bores of the air pipes.

\Vhen the liquid levels in the cans reach the lower ends of the air pipes the escape of air through said pipes will be, of course, cut off, and the remaining air in the cans will,

during the continued vingress of the paint, and until the liquid levels reach the lower,

ends of the adjusting nozzles 38, ascend through the paint in the filling conduits and outside of the pipes 47, and occasion bubbles on the surface of the paint in the reservoir close to the-respective air pipes.

\Vhen the liquid level in a can reaches the lip of the adjusting nozzle 38 the egress of air through the filling conduit will, of course, be cut off, and the flow of paintthrough the tilling conduit will thereupon cease owing to the resistance of the banked air in the top of the can, and within the associated air excluding collar, and the operator-in charge will know by the cessation of the bubbles that the liquid level in the can has reached said adjust-.

ing nozzle.

When the operator in charge has seen the bubbles appear and then ceaseinthe'vicinity.

of each of the cans, he will know that they have all been filled, as stated, to the levels of the lower edges of the adjusting nozzles within theni, and he will thereupon occasion the rotation of the shaft 24in the appropriate direction to cause the elevation of the reservoir away from the cans.

As will be understood, the supply conduits remain, when the cans have been tilled to the levels of the lips of the adjustinguozzles, full of paint, which, however, will not flow into the cans by reason of the resistance of the air cushions in the tops thercoflabove the levels of the lower edges of said nozzles, and whichair cushions are, of course, so to speak, continuous of the air cushions within the respective airexcluding collars.

lifted frornthe cans until'just after the valves Immediately, after the reservoir beginslto rise, the entrance mouths-of. the supply or filling conduits receive the temporarilystationary' valves til, the passage of the paint from the rservoir'into the supply conduits being thus shut' off, so that the final charges made to thecanswhen the'reservoir begins its upward movement,represent the amount of paint in thesupply conduits plus the very minute quantity passing into said conduits in the interval between the time the ascent beginsand the time the valves 49 are seated. That is to say, the paint ceases to flow into a can, as explained, quickly after the liquid therein'is so-high that it reaches the lip of the adjusting nozzle, and said can receives in addition to such'amou lit, the small additionalamount contained inthe supplyconduit,plus the minute quantity-which may-flow into the said conduit prior to the seating of-the valve 49-and which last mentioned amount may be very easily allowed-tor iu the setting of the parts. Such last 'mentionedamount obviously 'willdependupon the distance the reservoir must travel upward before the-valve 49 is seated, and the quickness .withwhich said travel is accomplished. As the distance from the valves. 49, when unseated, to their seats, when the parts are in the acting position shown in Figure 2, is short, and asthe, reservoir-may always be caused-to ascend at practically the same speed, the two factors affectingtheresultremain nni form,and hence said minute quantity will be a substantially uniform and determinable quantity.

As will befunderstood, the'cessation of the direct flow. of liquid from the reservoir to the position of the regulating adjusting nozzle 38 upon the supplycondnit, and said nozzle tnay be very accurately adjusted to any desired rotating it to the right or left.

' In the operation of filling a can the appa in the can will reach the. adjusting nozzle when the can has received the quantity-of liquid which will,with the slight amount then in the supply conduit and such minute additional amount as enters said condu t before the valve 49 is seated,'fill the can to case-of many liquids, is usually a fraction of an inch below the inner surface of'the can top. 1

through said conduits, allowsthe quantity of- The lips oi the air excluding collars are not interior Iof the can may be regulated by the,

set within its range of adjustment by simply H entering afterward, that is to say the amount ing with it said supplycond'uits, the elevation IIO ratus is to be so adj nsted thatthe liquid level the precise point desired, and which, in the As'will be understood, therefore, my apparatuswill automatically fill the canswith precision' up t'o'any desired level. a The springs 53 which encircle the air pipes 47, bear respectively against the spring plates and stops upon said pipes, and serve to force the valves 49 to their seats, assisting the natural grayitative tendency of said-valves and pipes. I

to As-thereservoir rises and after tlie valves 49 have found their seats, so that the further entryof paint to the filling conduits is precluded, the lips of the air excluding collars I areiifted away from the cans, and at about i 5 .the same time the end edges of the reservoir,

encountering the bars 56, causes the participation of said barsin the upward movement of the reservoir.

As the reservoir ascends the wheeled'car- 2o rier Sis moved alongits rails in one direction or the other, to convey the filled cans out from beneath the filling apparatus and a new set ofempty cans beneath said apparatus; the reservoir is thereupon again caused to descend and the operation repeated.

-As the reservoir ascends the upper end of each of the vertically movable rack bars en- .counters and raises the free ends of the two fdrip pan. branch arms which intersect its '0 path, and tilt said drip pan branch arms and the drip panarms with whichthey are respectively connected, upon or with respect to the pivotal connections 66 (Figure 2) between said drip pan armsand the wing plates and upon which pivotal connections said arms are adapted to have their peudulous movement. The throwing upward-of the free ends of the drip pan brancharms by the rack bars throws inward the lower ends of the drip pan o arms the lower ends of which are connected asexplained to the drip pans, 58. The arrangement and proportioning of the parts is such that when the rack bars come to rest in their upward movement the drip pans will 5 come to rest in line below the supply co'nduits and receive any drippings from said conduits. The tendency of the arms 59-, 60, isto hang in almost vertical position in line below the pivotal connections 66, and to return to.said position by gravity upon the drip pan'branch arms being no longer held up by the rack bars. As the-reservoir descends, therefore, the

drawing away of the vertically movable rack bars from the drip pan branch arms, permits the drip pan arms andpans to assume the positions they naturally occupy in line below the respective pivotal connections 66, the pans being thus self removing from the path of the descending reservoir.

, I prefer to provide the two drip pans 58, at one side of the. apparatus,'each with an outlet pipe 67, terminating over 'a drip collector 68 ,'-through which pipes drippings received in the pans58 are deliveredto said collector to be removed'at the convenience-of the operator. .Said collector (i8. is of such length that in all positions-of the drip pans the outlet ends of the pipes 67 will overhang it.

' vVthou it is desired,after the apparatus has charged cans with paint of one color, to can a quantity of paint of a different color, it IS desirable to remove the reservoir and to substitute a clean reservoir so that the last mentioned paint will not in beingcanned receive streakings or traces of the paint formerly dealt with by the apparatus.

To do this I swing the drip pan branch arms 61,62, outwardly into the position shown in dotted lines in- Figure 1, and thereupon,

rotate the shaft 24 in the appropriate direction until the reservoir is elevated within range of the books 64, the upper ends of the vertically movable rack members, in, such movement, passing u p through the openings 69, formed for them in the cross member as shown in Figure 1.

I thereupon release the books 64 from thei'i" p s-and engage them with the hand es.

70 of the reservoir. I then remove the nuts from the bolts 41- which pass from the permanent bottom through the detachable bot" tom of the reservoir, (Figure 3) and'thereupon reverse the rotative movement of the shaft 24, whereupon the enforced descent of theracli bars will occasion the descent, and separation from the reservoir, of the detachable bottom carrying the pipes 37, the adjusting nozzles, and the air excluding col- ,lars,'leavin g the reservoir with its pipes 35,

air pipes 47, and spring plates 52, suspended at the top portion of the framework.

When the detachable bottom with its associated parts has been lowered as far. as necessary to aiford space for the removal of the reservoir, said reservoir is lifted from the books (34:, and another reservoir provided with its own pipes 35 and 47, spring plates 52 and associated parts, is substituted, and suspended on the books 64; the detachable bottom is pipes 37 the pipes 35 and 47 of the newly applied reservoir and to be made fast to the permanent bottornof-the new reservoir by the bolts depending therefrom.

- -The books 64 are then disengaged from the handles 70 of the new or fresh reservoir and placed within their keepers, the reservoir from the supplementary frame 19-and replaced by others.

The shaft 24.1is atwhat-I term the right handend of' the machine provided with a driven gear'7l, in mesh with.whichis the driving gear 72, and connected with the shaft of said driving gear is a crank arm 73 of special construction. Said crank arm is 'fitte'd I10. thereupon again elevated to receive in its to the squared extremity ot the shaft lastj men-tionedin the vicinity of which are the two stops shown particularly in FigureslO.

and 11. U

Mounted in asuitable way in 'oron said crank arm is a longitudinally movable looking bolt 74 the inner end of which-is adapted to make alternatecontact with the upper end of an uppersto'p 75 and the lower end of'the lower stop 76.-

' An expansive spring 80 hearing against a' pin on said bolt 7.4 and afixed portionof the crank arm, tends to force said bolt constantly toward the inner end oi the arm.

' The Outer endof said bolt is-provided with a hook 77, by which it may readily be manually engaged anddrawn outward.

A pawl 78 pivotallymiounted on the outer I end portion of the crank arm has a nose adapt ed,.wl.en said bolt is drawn to outermost position, to enter a recessin said bolt and retain it in said position. The other end of said pawl has a handle piece 79 by which the throw of said pawl to either engage or release the bolt may readily be manually fiCGOlll' .pl ished.

The upper stop '75 is a fixture and may bc' integral with a plate SO'attached to the upright 2. 4 i a part of or carried on a slide plate islarranged to have sliding. movement withn'espect to the plate 80. 82 is a lug projecting from said plate 80. S3 is a screw shaft swiveled in said lug, and having an unthreaded advance extremity entered in a recess in the (plate 80, and an intermediate portion passed through and engaged with an internal thread of an opening in the slide plate 81. Rotation of said screw shaft will manifestly occasion the vertical movement of the plate 81 and vertical adjustment of the stop 76 carried on said plate. The stops 75, 76, are both in line with the bolt 74:, but said bolt when drawn out ward will in the rotation of the crank arm 7 clear said stops.

Rotation of the crank arm to the right occasions the elevation ot the reservoir. \Vhen the reservoir has reached the desired height the inner end of the crank handle will, as the apparatus is arranged, be in such position that the bolt 74: may engage the top of the stop '75.- t

The pawl 78 is thereupon manipulated to release said belt, which thereupon under the impetus of its spring, moves inward across the top of the stop '75, as shown in Figure 10. Said stop 75 therefore retains said crank arm, during the time the reservoir is up, against its tendency, due to the weight of the reservoir, to rotate to the left. and allow of thelowering of the reservoir.

\Vhen it 'is desired to lower the reservoir the 'bolt '74 is retracted and locked by the pawl. The crank is then rotated to the left, to allow of the descentof the reservoir to the position illustrated in Figure 4, two revolu- The lower stop 76 may beformd astions bcingrequired in a machine of the pro portions and arrangement illustrated, When the parts are in the set illustrated i itsaid Figure 4, the-crank arm will he in such position thatthe bolt 74 may engage beneath the stop '76. Thepawl'78 is thereupon rocked .to release said bolt, which thereupon under the impetus of its spring moves inward across the lower face of the stop 76., Said stop,'thereupon, acts .0. restrain any movement of the crank to the right, under the influence ofthe expanding tendency of the compressed or collapsed air excluding collars, transmitted to said crank through the reservoir, rack bars,

and the gears, and serves to secure-the parts againstthe tendency tobe elevated by said collars. I

As the fixed position of the crank arm after having been rotated to the left to lower the reservoir and its associated parts, determines the position in which the parts come to rest and the relation of the supplyconduits to 1 ie cans, (apart of course from independent ad-- justment of the nozzles 38, and the setting up ordown ot the cans by blocks beneath them), v

I find theadjustability of the stop 76 ausefnl feature as the point at which the'crank arm should come to rest with the reservoir in its lowest position, will vary as between sets of cans all of one size and sets of cans all of another size,subsequently operated upon, and by adjustment of said stop IAcan very readily and accurately control the point at which the crankarm and the-reservoir with its supply conduits shall thus come to rest.

It will now be understood that in my ap parat-us the filling reservoir with its so-called permanent-and so-called detachable bottoms operates in the filling of cans or the like, as a whole or unitary structure, the detachability of the detachable bottom only coming into play at times when it is desired to substitute one reservoir body for another. Also that the supply conduits constitute in eifect unitarystructures notwithstanding that IIO they, for the purpose of substituting one resvention, the term in its broadest signification being intended to cover a single thickness outlet pipe, as wellfas the double pipe illustrated.

Where a series of cans of different dimensions are to be filled, I prefer to so arrange them that thetops of all will be at a common level, and this result may, of course, be obtaincd by providing the carrier with blocks or supports placed bencath'the cans ot sizo I smaller than the largest, as shown particularly in Figure3.

As thersupply conduits will all contain,- when'the'paiut or liquid level in the cans when the paint or liquid thereupon ceases to flow through themabout thesame amount ofp'ai'ntorotherliquid,- and as suchainounts will, when they finally run into the cans as the supply conduits are elevated, have a greater effect in augmenting the liquid level in cans of small diameter'than they will in cans of larger diameter,:-I adjust or set the adjustable nozzles which operate in connec tion with the small cans farther down than those operating in connectionwith the large: Thereupon, when the liquid ceases to flow into the cans at the time the liquid levels therein 20' reach the adjustable nozzles, the liquid levels in the smaller cans will be proportionately ...lowerthan those of the larger cans.- Thereupon, when the final discharge ofthe con- .tents of the supply conduits to the cans takes place, the liquid levels in'all the cans may be brought-up to a point at a uniform distance from the-tops of'the cans, by reason of the fact stated, that the discharge from the sup- .ply conduits will increase the liquid levels in the small cans more than it will those of the large cans.

I When in the accompanying claims Irefer to liquid,-I intend the term to cover not only Y paint but any'liquider semi-liquidin connec- -tion with which the apparatus may be made useful.

It will, of course, be understood that in referring to the apparatus-as intended for filling cans and the like, the expression employed is to be construed broadly and is intended to cover any and all kinds of receptacles in con-.

nectiou with which the apparatus described may be employed.

Having thus described my invention, I
